The endocrine system glands and hormones that are released from them influence our entire body. It helps to regulate everyday things in our bodies, including the regulation of our mood, growth and development, tissue function, metabolism, sexual function and reproductive processes. The endocrine system is in charge of the body processes that happen slowly, including cell growth whereas the nervous system controls much quicker processes.

These two systems work together in order to keep the human body functioning properly. Without them functioning in sync together or properly, many problems can occur within the body. The nervous system controls the endocrine system, and without the endocrine system, the nervous system may not have enough of a specific hormone or chemical needed in order to work properly together.

This is essential to proper function of your body also because your nervous system senses pain. Without this, your body can go through major “pains” without sensing or feeling them, or even the opposite, and not feel and pain, or not receive enough sensations to keep it active and responsive. This is bad because your body is used to feeling sensations and it is very abnormal not to feel anything. Without feeling anything, the neurons are not stimulated, and the nervous system is practically pointless at that point in time.
